DETAILED DESCRIPTION [020] Figure 1 shows an exemplary embodiment of a bleaching assembly 100 that can be used for implanting a compression nail in an ankle or other suitable human tissues. The targeting assembly 100 may include a connecting rod 102 for connecting a first arm 104 and a second arm 106. In one embodiment, the first and second arms 104 and 106 can be produced from a radio translucent material. The first arm 104 may include a proximal portion 110 and a base portion 112, in which the base portion 112 of the first arm 104 is connected to the connecting rod 102. In an exemplary embodiment, the first arm 104 and the connecting rod 10 102 can be rotationally fixed relative to each other to provide enhanced stability. In another exemplary embodiment, the first arm 104 can be pivotally coupled to the connecting rod 102 and therefore operable to rotate around the connecting rod 15 102. The second arm 106 can include a proximal portion 114 and a portion of base 116, in which the base portion 114 of the second arm 106 is pivotally coupled to the connecting rod 102. In an exemplary embodiment, the proximal portion 114 of the second arm 106 can be operable to pivot about a geometric axis longitudinal 108 defined by connecting rod 102. For example, the second arm 106 can rotate from a first rotational position, as shown in Figure 1, to a second rotational position separated by a predetermined angular displacement 25. [021] Figure 2 shows an exemplary embodiment of the bleaching assembly 100, with the second arm 106 rotated to a second exemplary rotational position. In the modalities illustrated in 30 Figures 1 and 2, the first and second rotational positions have an angular displacement of 90 degrees. In other embodiments, the second arm 106 can be rotated to any position of rotation that is necessary to allow the desired approach to inserting a spindle. In an exemplary embodiment, the second arm 106 is operable to rotate around the longitudinal geometric axis 108 in predetermined angular displacement increments, such as 30, 45, 60, 90, or 180 degrees. A person of ordinary skill in the art would understand that the increments need not be equal, and the amount of predetermined angular displacement for each increment can be customized to meet the surgeon's operational preferences. [022] Referring to Figures 1 and 2, the first arm 104 may include at least one alignment hole 118 defined through the proximal portion 110 of the first arm 104, and the second arm 106 may include at least one alignment hole 120 defined through the proximal portion 114 of the second arm 106. The alignment holes 118 and 120 allow a surgeon to target, 20 drill and insert screws through the bone and into a compression nail (not shown) in the desired orientation, which will be discussed in more detail below. In the illustrated embodiments, each of the first arm 104 and the second arm 106 includes a plurality of orifices of alignment 118 and 120, respectively. In other embodiments, the first and second arms 104 and 106 can be configured to have equal or different numbers of alignment holes 118 and 120, respectively, which can be one, two, three, four, five, or more, depending on 30 surgical needs and the number of options desired or the relative geometry of any associated implant. [023] Figure 3 is a cross-sectional view of the target assembly 100 that illustrates a distance Dl between an alignment hole 118 of the first arm 104 and the base portion 112 of the first arm 104. Also shown in Figure 3 is a distance D2 between an alignment hole 120 of the second arm 106 and the base portion 116 of the second arm 106. In an exemplary embodiment in which the first arm 104 is rotationally fixed in relation to the connecting rod 102, D1 can be configured to be greater than D2 to reduce any misalignment of the alignment hole 120 due to the rotation of the second arm 106. It should be understood that the farther the alignment hole 120 is arranged from a point of rotation, the greater the magnification of any misalignment will be result. As such, it is desirable to configure the second rotating arm 106 to have a D2 less than the D1 of the first fixed arm 104. It should be understood that the end points of D1 and D2 can be defined in a number of ways. In the illustrated embodiment, the end points of D1 are the center of an alignment hole 118 and a point along the longitudinal axis 108 within the base portion 112. In one embodiment, an end point along the longitudinal axis 108 can approach a center of rotation of the first arm 104 or second arm 106. In another embodiment, the end points of D1 and D2 can be close to the alignment holes 118 and 120 and to the longitudinal geometric axis 108. [024] Figure 4 is an exploded view of the bleaching assembly 100 that shows exemplary mechanisms for connecting the first and second arms 104 and 106 to the connecting rod 102. As a person of ordinary skill in the art can see in Figure 4, 5 various mechanisms can be used to connect the first arm 104 to the connecting rod 102. In one embodiment, the connecting rod 102 and the first arm 104 can be modular components that are releasably coupled using any coupling mechanisms 10 known in the art. In another embodiment, the connecting rod 102 and the first arm 104 can be pre-assembled or integrally formed in one piece. [025] The connecting rod 102 and the second. . arm 106 can also be releasably coupled with the use of any suitable coupling mechanisms known in the art. As shown in the exemplary embodiment disclosed in Figures 3 and 4, a suitable mechanism is a closing mechanism. For example, connecting rod 102 can include a lock 124 and a plurality of recessed areas 122 defined on a circumferential surface of connecting rod 102. Lock 124 is operable to be received in one of the plurality of recessed areas 122 and engaging the base portion 116 of the second arm 106, thus maintaining the second arm 106 in a rotational position 25 around the longitudinal geometric axis 108. In one embodiment, the plurality of recessed areas 122 can be separated circumferentially by predetermined angular displacements, and the second arm 106 can rotate about the longitudinal geometric axis 108 in increments 30 substantially equal to the predetermined angular displacements. For example, lock 124 can be released from the recessed area 122 to rotate the second arm 106 until a predetermined angular displacement is reached, at which point the lock 124 would be received in another recessed area 5 122 and the second arm 106 would rest on a new one. rotational position. In one embodiment, lock 124 can be mechanically coupled to or a part of a manual switch 126, so that a surgeon can use switch 126 to remove lock 124 from recessed areas 122 and 10 to allow rotation of the second arm 106. For example, lock 124 may be a spring-loaded pin removable by pressure on a switch 126. As discussed above, several increments of angular displacements. . predetermined can be used, such as 30, 45, 60, 90, or 15 180 degrees. A person of ordinary skill in the art would understand that the increments need not be the same, and the amount of predetermined angular displacement for each increment can be customized to meet the surgeon's operational preferences. 20 [026] Referring to Figures 1 to 4, some embodiments of the bleaching assembly 100 may further include a compression element 12 8 and a recess 13 0 adjacent to the compression element 128. The compression element 128 can be coupled so as to screwable to connecting rod 102, and connecting rod 102 can be arranged through a central recess in the hollow 130. The compression element 128 may comprise an internally threaded surface operable to be compatible with an externally threaded portion 132 of the connecting rod. connection 102. 30 As such, a rotation of the compression element 128 would translate the concavity 130 along the longitudinal geometric axis 108. The illustrated compression element 128 may be desirable in some modalities due to its ease of adjustment, but, in other modalities, other types of compression elements can be used to transfer the hollow 130. [027] Some embodiments of the bleaching assembly 100 may further include a rod 140, and the connecting rod 102 may have a central hole which receives the rod 140 in it. The rod 140 may include a tip 142 that extends upwardly out of a top gap of the connecting rod 102 and adjacent to a plurality of tabs 144 disposed on an end portion of the connecting rod 102. The tip 142 can be threaded to engage complementary threads of an end portion of a nail (not shown) and rotate the nail to lock against the tabs 144. [028] In some embodiments, the second arm 106 may further include an angular adjustment mechanism 134 operable to secure an oblique orientation guide (not shown) along an oblique geometric axis (not shown) that is offset from the longitudinal geometric axis 108. As such, a spindle (not shown) can be inserted in an oblique orientation as long as it is not blasted into a nail (not shown), which will be further discussed below. [029] The use of the bleaching assembly can allow for numerous advantages, which will be discussed with reference to an exemplary embodiment of a compression nail system 200 shown in Figure 5. The compression nail system 200 includes a bleaching assembly 201 , which is substantially similar to the targeting assembly 100 shown in Figures 1 to 4. The targeting assembly 211 includes a connecting rod 220 to connect a first arm 204 and a second arm 206, and 5 each of the first arm 2 04 and the second arm 026 can include a plurality of alignment holes 218 and 220, respectively. The first arm 204 can include a proximal portion 210 and a base portion 212, which is connected to the connecting rod 202. In one embodiment, the first arm 204 and the connecting rod 202 can be rotationally fixed one with respect to to the other. In another exemplary embodiment, the first arm 204 can be pivotally coupled to the connecting rod 102 and thus be operable to rotate around the connecting rod 15 202. The second arm 206 may include a proximal portion 214 and a portion base 216, which is rotatably coupled to the connecting rod 202. In one embodiment, the proximal portion 214 of the second arm 206 may be operable to rotate about a longitudinal geometric axis 208 20 defined by the connecting rod 202. In an exemplary embodiment, the second arm 206 is operable to rotate around the longitudinal geometric axis 208 in increments of predetermined angular displacements, such as 30, 45, 60, 90, or 180 degrees. The second arm 206 can be releasably coupled to the connecting rod 202 according to the principles disclosed in the present disclosure to allow incremental rotation of the second arm 206. [030] Similar to the target assembly 100, the target assembly 201 may further include a compression element 228 and a hollow 230 adjacent to the compression element 228. The compression element 228 may be threadably coupled to the connecting rod 202, and the connecting rod 202 can be arranged through a central gap of the concavity 230. As such, a rotation of the compression element is 228 would translate the concavity 230 along the longitudinal geometric axis 208. In one embodiment, the compression element 228 may comprise an internally threaded surface operable to be compatible with an externally threaded portion 10 232 of the connecting rod 202. [031] Referring now to Figure 5 and Figure 6, in addition to the bleaching assembly 201, the compression nail system 200 can also include a nail 240 seated next to a rod end portion of connection 202. In a In this embodiment, the targeting assembly 201 may include a rod 290, and the connecting rod 202 may have a central hole which receives the rod 290 therein. The rod 290 may include a tip 292 that extends upwardly out of a top gap of the connecting rod 220 and 20 adjacent to a plurality of tabs 2 94 disposed on an end portion of the connecting rod 202. The tip 292 can be threaded to engage complementary threads of an end portion of nail 24 0. A rotation of rod 290 would rotate nail 240 to lock it 25 against tabs 294. As such, nail 240 can be aligned substantially along of the longitudinal geometric axis 208. [032] When the nail 240 is seated on the end portion 260 of the connecting rod 220, a longitudinal opening 262 of the rod 290 can find an inner opening 264 of the nail 24 0. As such, the inner opening 264 of the nail 240 it is accessible from the outside of the bleaching assembly 201 through the longitudinal opening 262 of the rod 290. [033] Turning to Figure 5, in one embodiment, nail 240 may include a plurality of spindle holes 242, 244, 246, 248, and 250 defined therein. In one embodiment, the first and second spindle holes 242 and 244 can each define a lateral geometric axis (not shown) orthogonal to the longitudinal geometric axis. In one embodiment, the first and second spindle holes 242 and 244 can define lateral geometric axes (not shown) that are orthogonal to each other. The first spindle hole 242 can be oriented so that it is in lateral alignment with a first alignment hole 220a when the second arm 206 is in a first rotational position. The second spindle hole 244 can be oriented so that it is in lateral alignment with a second alignment hole 220b when the second arm 206 is in a second rotational position. In one embodiment, the first rotational position can be the rotational position of the second arm 206, as shown in Figure 5, in which the second arm 206 is angularly displaced from the rotational position of the first arm 204 by approximately 90 degrees. In one embodiment, the second arm 2,066 can be rotated to a second rotational position where it would be angularly displaced from the rotational position of the first arm 204 by approximately 180 degrees. The angular displacements of 90 and 180 degrees for the first and second rotational positions, respectively, are merely exemplary modality, and a person of ordinary skill in the art would understand from the present disclosure that the first and second rotational positions 5 of the second arm 206 can be a variety of angular displacements of the first arm 204. Depending on the orientations of the first and second spindle holes 242 and 244 of the nail 240, the first and second rotational positions of the second arm 206 can be adjusted accordingly. [034] Nail 240 can be any compression nail known in the art, including nails for ankle arthrodesis or other orthopedic procedures that require compression of one or more bones. It should be understood that a nail 240 of a variety of lengths and diameters can be attached to the connecting rod 202. Targeted through the alignment holes of the first and second arms 204 and 206 of the bleaching assembly 201, bone screws (not shown) 20 can be inserted through the various spindle holes of nail 240, thereby locking nail 240 to a patient's anatomy. In an ankle arthrodesis procedure, there are typically several screws that are inserted into the reported bones (in this case, the tibia, talus, and calcaneus) and these screws 25 are sometimes placed in an intermediate-lateral direction (M / L) OR anterior-posterior (A / P). This variation in M / L and A / P spindle settings can have as much to do with anatomy as with the surgeon's preference, and the bleach assembly 201 of the nail system 200 can allow the surgeon to choose the best and most appropriate option based on patient and surgical preferences. In one embodiment, tibial screws, the talar spindle, and the upper calcaneal spindle can be implanted in an M / L configuration via nail 240. In another modality, 5 surgeons can approach in a lateral-intermediate configuration (L / M ). [035] Conventional blanking mounts may include blanking arms that rotate around the nail to accommodate an M / L or A / P placement of screws. 10 But a problem associated with conventional bleaching assemblies is that when the arm is rotated, there is a risk that the alignment of the bleaching arm holes in relation to the holes in the nail is compromised. This is of particular concern for the closest holes 15 in the bleaching arm and the nail as they are typically the furthest from a point of rotation and are usually, therefore, the most affected by increased misalignment. In this respect, the advantages of the bleaching assembly 201 may include the stability 20 provided by the first arm 204 and the connecting rod 202 being rotationally fixed in relation to each other. As such, alignment holes 218, which may be the closest alignment holes in blasting assembly 201, are rotationally fixed relative to nail 240, thereby reducing or eliminating the risk of misalignment due to rotation of the first arm 204 and resulting in high targeting accuracy. The second arm 026 can be allowed to rotate around the nail 240 to accommodate various spindle options, as discussed in the present disclosure, including the distal screws around the joint (for example, talar, calcaneal M / L and calcaneal A /P). As the holes 220 of the second arm 206 are closer to the point of rotation of the second arm 206, they are less susceptible to blurring inaccuracies due to rotation than the holes 218 of the first arm 204 would be. [036] Similar to the target assembly 100, the target assembly 201 may include an angular adjustment mechanism 234 operable to secure an oblique orientation guide (not shown) along an oblique geometric axis (not shown) that is offset from the longitudinal geometric axis 208. In some modalities, screws (not shown) can be inserted posteriorly-anterior (P / A) from the back side of the heel upwards towards the talus. One reason for this is to provide additional fixation and compression through that joint, but a difficulty in inserting fixing screws in this way may be the orientation. After the nail and associated screws have been inserted, there is only a small amount of "free space" left to use such screws. It is desirable to avoid drilling into existing metal, such as the existing nail 240 and associated screws (not shown). In this respect, the angular adjustment mechanism 234 is operable to target a spindle along an oblique geometric axis deviated from the longitudinal geometric axis 208, thus avoiding targeting nail 240 and, instead, targeting each side of nail 240 . [037] An exemplary modality of use of the nail compression system 200 will be discussed with reference to Figures 7A to F. It is shown in Figure 7A is the ankle of a patient, who has been surgically prepared to include an opening 302 defined through the calcaneus , talus and tibia to receive nail 240. In the embodiment illustrated in Figure 7A, nail 240 is attached to the bleaching assembly 201, with both the first and second arms 204 and 206 aligned in the same plane. Nail 240 can be inserted into opening 302 by passing nail 240 through a guide wire 304 disposed through a longitudinal opening (shown in Figure 6) of the connecting rod 202. In one embodiment, the first and second arms 204 and 206 can be angularly displaced from each other as nail 24 0 is inserted (not shown). In one embodiment, nail 240 can be inserted without the aid of guide wire 304. [038] After nail 240 is inserted, the first arm 204 can be positioned for an M / L approach to the tibia screws (not shown), and the second arm 206 can be rotated to a first rotational position for an L approach. / M for a talar spindle 260, as shown in Figure 7B. In another embodiment, the first arm 204 can be positioned for an L / M approach, and the second arm 206 can be rotated to a rotational position for an M / L approach. With the second arm 206 in the desired rotational position, a spindle guide 262 can cooperate with the second arm 206 to target and insert the talar spindle 260 through a corresponding spindle hole in the nail 240 and the talus. Once the talar spindle 260 is inserted, the orientation and depth of the nail 240 relative to the patient's anatomy are established. [039] Turning to Figure 7C, in the illustrated embodiment, two spindle guides 266 can cooperate with the first arm 204 to target and insert tibial screws 280 through corresponding spindle holes in nail 240 and tibia. As discussed above, the 5 tibial screws 280 can be implanted in an M / L approach, as shown in Figure 7C, or in an L / M approach. After insertion of the tibial screws 280, internal compression of the tibial-talar joint can be performed by activating a suitable internal mechanism (not shown) of nail 240. A variety of internal mechanisms can be used to effect internal compression on the nail. compression nail system 200. These internal mechanisms are well known in the art and therefore would be. . described here. After the desired internal compression is effected, the external compression of the subtalar joint can be effected by adjusting the compression element 228 to advance the concavity 230 in a proximal direction until the desired compression is achieved. [040] Turning to Figures 7D and 7E, the 2 0 second arm 2 06 can be rotated to the desired rotational positions to allow the insertion of two calcaneal screws 268 after the internal and external compressions have been achieved. In the illustrated embodiment, the second arm 206 is rotated to the first rotational position 25, as shown in Figure 7D, for the insertion of a first calcaneal spindle 268 in an L / M approach, and then the second arm 206 is rotated for a second rotation position, as shown in Figure 7E, for the insertion of a second calcaneal spindle 268 in a P / A approach. 0 30 blanking and insertion of the calcaneal screws 268 can be performed with the direction of a spindle guide 270. It must be observed in other modalities that the order of insertion of the first and second calcaneal screws 268 can be varied and the approach of insertion can be be varied 5. [041] Turning to Figure 7F, an oblique spindle 272 can be implanted to obtain greater rigidity of the construct and to maintain the compression before releasing the external compression. As discussed above, an oblique blanking guide 274 coupled to the angular adjustment mechanism 234 can be used to target and insert the oblique spindle 272 along an oblique geometry axis (not shown) offset from the longitudinal geometry axis 208 (no. shown), thus avoiding targeting nail 240 and, instead, targeting each side of nail 240. In one embodiment, the angular adjustment mechanism 234 may include an operable guide button for adjusting the angular orientation of the targeting guide oblique 274.
